Sculpting with porcelain is possible if you understand the character of the clay. Antoinette Badenhorst, ceramic artist from Mississippi uses different techniques to build her porcelain sculptures. Balloons are one of the techniques.
She demonstrates in this video how to use a balloon to make a translucent porcelain bowl that can be used as part of a bigger handmade project. She shows in the video that the balloon shaped bowl may also be used as part of a porcelain dinner set. The size and shape of the balloon will dictate the size and shape of the bowl.
